Definitions

• the invention relates to a nitrogen-free substance for Use as a spreadable fertilizer, soil additive, Culture substrate or plant auxiliaries containing 50 to 90% by weight of rock flour, preferably from a mixture of different rock minerals, 5 to 50% by weight 3-layer clay minerals, 1 to 25% by weight of zeolites and 1 up to 5% by weight of binder, in particular dextrin, and nitrogen-binding Bacteria.
• the invention further relates to a process for producing such a nitrogen-free Substance.
• the nitrogen supply through fertilizers reduce to reduce the nitrate load and still the supply of crops with nitrogen ensure not to the growth-promoting effect of main and trace nutrients on crops to have to do without.
• the object is achieved in that the above described Substance also 0.1 to 10% by weight of a dry admixed sulfate mixture containing magnesium, Sodium, copper, manganese, zinc and / or iron sulfate includes.
• Substance for use as a spreadable fertilizer, soil additive, Culture substrate or plant aid is Rock powder, preferably from a mixture of different finely ground rock minerals, in a proportion of 50 to 90% by weight with 3-layer clay minerals in a proportion of 5 to 50% by weight, zeolites in one Proportion of 1 to 25% by weight and binder, in particular Dextrin with the addition of water, in a proportion of 1 to 5% by weight and nitrogen-binding bacteria are mixed. Then a sulfate mixture in a proportion of 0.1 to 10% by weight dry mixed, the magnesium, sodium, Includes copper, manganese, zinc and / or iron sulfate.
• the sulfate compounds dry ensures that no ionic equilibrium is formed can and the various mixed sulfate compounds each directly related, proportional to each other based on their element order, to the effect comes in the plant.
• the recording in turn hangs directly on the intensity of the light source (solar radiation) from.
• the intensity of the light source solar radiation
• the amount of fertilizer by up to 40% compared to conventional used amount can be reduced without the Fertilization decreases.
• This dry mix also promotes the so-called Antagonism synergism effect and therefore it can too no overreaction (over-fertilization of a single nutrient) the enrichment comes or becomes in the plant of an individual element.
• the effect of each Nutrients remain through the dry mixing receive.
• the plant can freely choose which nutrients can be included and you can see that in periods prolonged drought of water stress (Drought) is no longer so important (protective wilt occurs later) and therefore dry periods of the Plants survive better.
• the sulfate also reduces the water content through formation of hydrated water, which has a positive effect on the shelf life effect.
• the substance according to the invention mobilizes those present in the soil Nutrient reserves (e.g. P, K, trace elements) and also contains important main and trace elements in plant-available form. Due to its high Silicic acid (silicon) strengthens the plant tissue. The fabric improves the floor structure and promotes soil life.
• soil Nutrient reserves e.g. P, K, trace elements
• Silicic acid silicon
• the fabric improves the floor structure and promotes soil life.
• the substance increases the vitality of the plants. Cell walls are more developed, so the application rates of fungicides and growth regulators significantly reduced or sometimes even omitted. With the Application of the substance can also be used for maintenance liming be saved. The fabric thus enables significant cost savings.
• the sulfates increase the effectiveness of the substance and accelerate it the provision of various nutrients in the soil nutrient balance.
• the substance is preferably in the form of granules onto which the nitrogen-binding bacteria with a nutrient solution are sprayed on, preferably from acetates and molybdate consists.
• the granulate is applied like a basic fertilizer. Due to its granulation, the granulate can be used with everyone Spread the fertilizer spreader.
• Granules with the following proportions were used for experimental purposes manufactured. 25% Dolomite, 25% Biolit (half pH-neutral or half acidic basalt), 40% clay compounds (expanded clay content 15%., 25% illite-vermiculite mixture, the mixture of illite and vermiculite from 5 - 54% illite and 10 - 81.7% vermiculite ) and 4% quartz-free zeolites (clinoptilolite - natural zeolite) were treated with 2% dextrin Binder (from starch from agricultural crops won) and 1% water mixed. And there were 3% sulfates added dry.
• the nutrient content was as follows: Main nutrients: Micro-nutrients: SiO 2 30.00% silica iron CaO 16.20% calcium manganese MgO 9.40% magnesium zinc K 2 O 0.41% potassium copper P 2 O 5 0.19% phosphate boron molybdenum cobalt selenium
• a granulate produced therefrom was treated with a nitrogen-binding Solution containing bacteria (Azotobacter) sprayed and used as fertilizer when cultivating numerous agricultural crops Cultures used on a trial basis.
• Bacterial nutrient solution (Azotobacter - Azotobacteraceae strains) was sugar water with Mg, Na, Fe, Cu, Zn, Mn and Mo enriched that previously digested with an acetic acid were (acetate).
• Bacterial nutrient solution was sugar water with Mg, Na, Fe, Cu, Zn, Mn and Mo enriched that previously digested with an acetic acid were (acetate).
• In this nutrient solution were at a temperature of approx. 25 ° C Bacteria added for reproduction. After a few days with good propagation, the liquid was reduced by approx. diluted two thirds with water, and sprayed on the granules used. It showed good effects the fruit quality and yield amount and an improvement the soil quality.
